The author of the poem I don't expect anything in return is (Wang Guozhen). From the poem, I realized that one should make contributions to society and others as much as possible, without expecting anything in return, so as to make his ordinary self (sublime). One sentence that reveals this truth in life is (people may not make themselves great, but they can make themselves lofty).
